Overview

NCI Definition: A glial tumor of the brain or spinal cord showing astrocytic differentiation. It includes the following clinicopathological entities: pilocytic astrocytoma, diffuse astrocytoma, anaplastic astrocytoma, pleomorphic xanthoastrocytoma, subependymal giant cell astrocytoma, and glioblastoma. [1]

Astrocytic tumors most frequently harbor alterations in TP53, CDKN2A, PTEN, EGFR, and CDKN2B [2].

Most Commonly Altered Genes in Astrocytic Tumor

TP53 Mutation, TP53 Missense, TP53 c.217-c.1178 Missense, CDKN2A Loss, and CDKN2B Loss are the most common alterations in astrocytic tumor [2].
